Характеристики
● Verification of single-phase, three-phase three-wire, three-phase four-wire system active and reactive inductive energy meters and electronic energy meters.
● Simultaneously verify the errors of active and reactive energy meters, and simultaneously verify the errors of the main and auxiliary meters and automatically calculate the rounding errors
Difference. The active and reactive power errors of the load management terminal and the distribution transformer monitoring and metering terminal are verified at the same time.
● Adopt digital true reactive power measurement technology to increase the reactive power accuracy to 0.1%.
● Before the metering device is powered on or during power outage maintenance, wiring inspection, TV and TA magnification check, and secondary circuit testing
impedance.
● Check the energy meter constants.
● Meter clock error check, broadcast school time.
